Again, I find an article advertisement in our local beekeepers newsletter touting the product "Mite Solution". This time there are some details: it contains petroleum jelly, some "NATURAL BOTANICAL EXTRACT" , and is applied on mouse guards or queen excluders. It has a US patent pending number. Pest control inferences are primarily for tracheal mites and varroa mites (featured at the top of the flier). In the body of the text claims for reductions of chalk brood, EFB, AFB, and nosema are made, as the product is purportedly a "natural fungicide and antiseptic". Testimonials are included, but the manufacturer/distributor claims it can't be registered as a "miticide" until $2,274,500 (US) in registration fees are paid. Is there >anything< to back up this product or is it a total scam? Whitney Cranshaw Department of Entomology Colorado State University Ft. Collins, CO 80523 [log in to unmask]
